TIP FOR THE ENDS OF PNEUMATIC-TIRE TUBES.

SPECIFICATION forming part of Letters Patent No. 709,994, datedSeptember 30, 1902.

Application filed April 28, 1902.

To all whom it may concern:

Be it known that LJOSEPH GEORGE MooMY, a citizen of the United States,residing at Erie,

' in the county of Erie and State of Pennsylvania, have invented new anduseful Improvements in Tips for the Ends of Pneumatic-Tire Tubes, ofwhich the following is a specification.

This invention relates to tips for the ends of pneumatic-tire tubes; andit consists in certain improvements in the construction thereof, as willbe hereinafter fully described, and pointed out in the claim.

The invention is illustrated in the accompanying drawings, as follows:

Figure 1 shows a side view of the tube having the tip formed accordingto my invention thereof. Fig. 2 shows a plan view of the same. Fig. 3shows a plan view of the tip; Fig. 4:, a side view of the same.

A marks the tip, and B the tube. The tip is formed in the shape of afiat thimble of fiber-stock that is, of a mixture of rubber and unwovenfiber. Preferably the fibers are arranged lengthwise of the tip, so thatthe tip may have elasticity in a transverse direction and but verylittle endwise. The fiber is brought to this position in the process ofcal- Sarial No; 105,016. (No model.)

endering. By the use of fiber-stock greater strength may be given to theend of the tube with very little additional weight or bulk, and as theend of the tube is subject to an end strain of more or less extent,depending upon the location of the ends of the tubes relatively to eachother, the use of the fiber-stock prevents'undue stretching in thisdirection, and where the fiber-stock is used with the fiberslongitudinally arranged the end stretching is prevented withoutaffecting the transverse elasticity of the tip, so that the space in thetire is completely filled. The use of the stock also strengthens the endof the tip for insertion or removal from the tire. This is particularlytrue of the tips having the fiber arranged in alongitudinal direction.

What I claim as new is A tip for pneumatic-tire tubes formed offiber-stock with the general longitudinal direction of fibers.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

JOSEPH GEORGE MOOMY.
